Compact LCOS Microdisplay with Fast CMOS Backplane for High-Speed Light Modulation

Researchers from the Fraunhofer Institute for Photonic Microsystems IPMS, in collaboration with HOLOEYE Photonics AG, have developed a compact LCOS microdisplay with high refresh rates that enables improved optical modulation. This innovative microdisplay will be presented for the first time at the 31st International Display Workshops (IDW) 2024 in Sapporo, Japan.

LCOS microdisplays are characterized by their low power consumption, small size, and lightweight design. They are used in switchable adaptive optics, particularly as phase modulators, and as projection displays in augmented or virtual reality (AR/VR). Phase modulators, also known as spatial light modulators (SLMs), are used in biological imaging and microscopy, among other applications, for wavefront correction and beam shaping. The goal is to improve image resolution, minimize distortions caused by biological tissue, or protect samples. The new LCOS microdisplay from HOLOEYE and Fraunhofer IPMS utilizes an innovative CMOS backplane that enables high-speed light modulation….
